Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical technology, in particular to a clinical puncture device for cardiovascular medicine. Background Art
[0002] Pericardial effusion is usually caused by infectious factors, non-infectious factors and other inducements, such as bacterial and viral infection, parasitic infection, tumors, chest surgery, etc. In cases of small amounts of pericardial effusion, it usually does not require treatment. When the pericardial effusion is large, it will compress the normal functioning of the heart and requires human intervention to drain it out to ensure the safety of the patient.
[0003] During the puncture and extraction of pericardial effusion, a syringe is usually used for extraction. When extracting through the syringe, the medical staff needs to hold the syringe with one hand and pull the piston handle connected to the piston shaft with the other hand. Pulling the piston handle during extraction will inevitably cause the puncture needle to shake, thereby causing secondary tissue damage and increasing the patient's pain. In addition, the syringe capacity is limited and multiple extractions are required, which makes the extraction process discontinuous and reduces the extraction efficiency. Especially for patients infected with viruses and bacteria or with infectious diseases, the needle will be exposed to the air environment during multiple extractions, and the effusion will also be exposed to the air environment during drainage, thereby increasing the risk of infection. For this reason, we propose a clinical puncture device for cardiovascular medicine. Summary of the Invention
[0004] The present invention aims to provide a clinical puncture device for cardiovascular medicine to address the problems raised in the aforementioned background art, such as the inevitable shaking of the puncture needle when pulling the piston handle during extraction, which can cause secondary tissue damage, an inconsistent extraction process, and the exposure of accumulated fluid to the air during drainage, thereby increasing the risk of infection.
